A STRAIN GAUGE PAIN STIMULATOR
Psychophysiology, 1971ABSTRACTFocal pressure, applied to the skin over bone, is a method of evoking experimental pain of an “aching” nature in which actual receptor stimulation is closely related to the applied stimulus. Methodological faults in previous applications of this method are eliminated by a pain stimulator which utilizes a bonded strain gauge.

Strain Gauge Amplifier Circuits
IEEE Transactions on Instrumentation and Measurement, 2013This paper presents several amplifier circuits for use with strain gauges. The circuits are inherently linear, produce four times the output of the standard Wheatstone bridge, and can easily be extended to accommodate multiple strain gauges. The implementation platform is the low-cost operational amplifier instead of the more expensive instrumentation ...

The Validity of Strain Gauge Plethysmography
Scandinavian Journal of Clinical and Laboratory Investigation, 1972A unique possibility of testing the validity of the strain gauge plethysmograph was found in regional perfusion of the human limb. It was possible to vary the inflow of the limb and at the same time record the peripheral flow with a strain gauge plethysmograph on the calf.

Automated strain-gauge plethysmograph
Medical & Biological Engineering & Computing, 1978An automatic 2-channel strain-gauge plethysmograph, based on an absolute resistance measurement technique, will be described in the paper. This device is compact, easy to use, provides inherent self-calibration for any gauge and any length of that gauge, automatically performs the measured cycle, and generates annotated graphical printouts of the ...

A strain indicator for semiconductor strain gauges
Journal of Physics E: Scientific Instruments, 1977A strain indicator comprising a constant-current source has been designed for use with semiconductor strain gauges. The instrument has provision for measuring a maximum of 1000 microstrain in ten decade ranges. It incorporates facilities for correcting for the spread in gauge resistance and gauge factor.

The electric strain gauge ballistocardiograph
American Heart Journal, 1950Abstract Since the recording of the first ballistocardiogram by Gordon, 1 the recoils of the body from heart movements and circulatory impacts have been studied with various types of apparatus. Horizontal ballistocardiographs in the form of a bed or table have been suspended from the ceiling or some supporting frame-work 1–9 or supported upon steel ...

Thermochimica Acta, 1978
Abstract Weighing with strain gauges is shown to have some very attractive features. An analysis is given of the limitation of the sensitivity due to various noise sources. It is shown that it is possible to use strain gauge balances somewhat below the milligram region.

Strain distribution in and around strain gauges
Journal of Strain Analysis, 1972The interaction between a strain gauge and its substratum is investigated for the special case of a one-dimensional gauge adhesively bonded to a half-plane. The influence on the strain distribution of the properties of the underlying material, of strain-gauge design, and of adhesive properties is demonstrated by numerical examples.

Gauge fields and strain engineering
2012We discuss the physics of pseudomagnetic field,s which can be induced in graphene by applying strains, and show how they can be used to manipulate electronic transport through graphene heterostructures (strain engineering). We consider strain-induced pseudo-Landau levels, which were observed in graphene, and discuss the related valley quantum Hall ...
